300W to 450W: 20 Power Supplies on the Test Bench

Seasonic S12II 330W
We tested the Seasonic S12II a while back and we liked it so much that we awarded it our Gold Editors' Choice Award. It seems that this series is not doing as well in the market now, since we have heard more negative feedback lately. Now that Seasonic announced an 80 PLUS Gold power supply series for early next year we want to have a last look of this fading series to get a better comparison to other units in this field. It comes in the typical black and with a ventilated back.
Both previously shown units from PC Power & Cooling and Silverpower are made by Seasonic and now we have the retail version from this manufacturer. The design is the same as we saw earlier, but this time we see better components and other small changes. It's clear that an ODM manufacturer also selling its own products wants to have the best components and technology for their retail power supplies. The main cap is made by Hitachi and the secondary caps also come from Japan and are made by Chemi-Con. Seasonic also includes all solid capacitors for the 12V rails. The fan is made by Adda, who supplies most of Seasonic's fans.
The Seasonic S12II 330W comes with the typical six Molex connectors and four SATA connectors. The 6-pin PEG connector is 60cm long, which is good if you want to guide the cable harness nicely through your chassis while trying to optimize airflow. The 24-pin connector is at 55cm, which is good for larger cases.

We cannot run after every brand there is and if those companies don't come to us... there are surely many more missing but we can only test products from companies that are actually interested in us testing their stuff. We had an Akasa unit before though...boboko - Sunday, January 4, 2009 - link
>"We cannot run after every brand there is and if those companies don't come to us..."I guess that is the problem with almost all review sites. And the worst thing is not that you skip the smaller guys, but that what you are reviewing is not off the shelf, it's sent to you buy a company that wants a good review. So even if they have rotten quality control, and half their stuff is DOA, you know the one they send you has been triple checked and fine tuned. Not your fault, but to me the reliability is MUCH more important than a few extra watts or a few less decibels, and there's just no way to get good data on that.

If you read the reviews here, you'd know that this assumption is false in general. AT has had junk on their bench on more than one occassion - if every supplier would do what you claim, all reviews would take place in happy bunny land where everything is dandy and no negative notion is possible. But thats not the case.Surely there will be those who go the extra mile to make their product look better than it is off the shelf, but you just cant hide every trace of incompetence and bad quality.
Much like we cant expect a review site buy every piece of hardware to test it and hope they can re-sell it without a loss.

I'm just curious why the "old" version of the Antec Earthwatts 430 was dug out and retested since Seasonic is no longer the OEM for it but now has Delta as the OEM supplier and has been for many months now.Seems it'd be only fitting that the "new" version would be tested instead of a version no longer being made or sold, except as NOS (new old stock).

If only "someone" could send it to us :] I will make sure to get new revision on time, you're totally right.sprockkets - Wednesday, December 31, 2008 - link
What were those bad things happening to the SII Seasonic PS?JarredWalton - Wednesday, December 31, 2008 - link
I believe Christoph is just saying that he's received an increase number of email messages from people saying that their Seasonic PSUs have failed. It's anecdotal at best, and it could just be a case of more people buying their PSUs and thus a small fraction that fails can still result in more complaints than before.Christoph Katzer - Wednesday, December 31, 2008 - link
Yes ;)There was a revision in the beginning that had problems with certain motherboards somehow, something to do with the "power good" signal. They've upgraded the series long time ago though.

I'd just ordered some new parts, including a CX400 about 30 minutes before I saw this article come up.Nice to see that my choice seems fairly solid.
I'm sure this article will be relevant for other people as well.
